Generally speaking, the test conducted to evaluate and analyze the reliability of electronic products is called reliability test. It is to predict the quality from the delivery of products to the end of their service life. After selecting the environmental stress with high similarity to the market environment, set the degree and application time of environmental stress. The main purpose is to correctly evaluate the reliability of products in a short time as possible.

For products, the higher the reliability, the better. The reliability test report can objectively point out that the product works normally for a long time. Generally speaking, the cost of R & D and production will be higher, but the later maintenance cost will be less; Generally, the cost of R & D and production of products with low reliability will be lower, but the later maintenance cost is also higher. In professional terms, it means that the higher the reliability of the product, the longer the product can work in fault-free state.

1. Climatic environment test:High temperature test, low temperature test, temperature and Humidity Cycle / constant damp heat test, cold and heat shock test, rapid temperature change test, low air pressure test, photoaging test, corrosion test, etc.

8. Electrical performance test:Temperature rise test, withstand voltage test, insulation resistance test, dielectric strength test, contact resistance test, surface resistivity test and grounding resistance test.

9. Failure analysis test:Surface / polar surface micro measurement and analysis, nondestructive measurement and analysis, electrical performance measurement and analysis, physical performance measurement and analysis, welding process measurement and analysis, PCB / PCBA measurement and analysis, electronic components measurement and analysis, plastic / rubber / polymer materials measurement and analysis, metal materials measurement and analysis.

The development of reliability engineering can drive and promote the development of product design, manufacturing, use, materials, technology, equipment and management, and raise electronic components and other electronic products to a new level. Reliability test is mainly an activity to ensure that the product maintains functional reliability in all environments such as expected use, transportation or storage within the specified service life. It is to expose the product to natural or artificial environmental conditions to undergo its action, so as to evaluate the performance of the product under the environmental conditions of actual use, transportation and storage, and analyze and study the influence degree and action mechanism of environmental factors.
